Stay safe and stylish

In Hong Kong and many other places around the world, masks have become an essential part of our everyday attire, incorporated into the checklist of items that we can never leave the house without. While covering up half of our faces with a mask can be a little inconvenient, it can also be a new avenue for spicing up your style while protecting yourself and others.

Our DET30™ anti-bacterial cotton masks are designed for comfort, style, protection in equal measure, coming in trendy colors that you can match with different outfits. Taking the environment into consideration, we’ve created masks that are reusable up to 30 times while maintaining their protective properties. Buy from our range of high-quality cotton masks online today, available in Hong Kong and select locations in Asia.

A staple for everyday protection, DET30™ is an anti-bacterial, and reusable 3-ply cotton mask. It is made up of an outer layer that features anti-bacterial and water-repellent treated fabric; a middle layer that creates a barrier to obstruct droplets; and an inner layer of light woven cotton for high breathability and comfort while keeping you safe. The DET30™ comes in one size with an adjustable strap and five solid colors.

DET30™ PLUS is a heavy-duty version of the original DET30™ made for advanced protection. Adding on to the anti-bacterial and water-repellent technologies from the original reusable cotton mask, DET30™ PLUS boasts enhanced bacterial filtration efficiency (BFE) of over 95% and a PTFE nanomembrane in the middle layer, achieving particle filtration efficiency (PFE) of over 70%. The DET30™ PLUS is available in one size with an adjustable strap. Choose from two solid colors—navy or white.

An anti-bacterial and reusable mask that molds to the shape of your face, DET30™ PLUS 3D excels in both performance and comfort. Providing the same advanced level of protection as DET30™ PLUS, our 3D version has an ergonomic cut that adjusts to the contours of your face for exceptional comfort and breathability. To upgrade your mask-wearing experience, DET30™ PLUS 3D is available in three sizes and three solid colors—black, white, and navy.

DET30™ Summer Cool makes wearing masks in Hong Kong’s summer heat a breeze. Lighter and cooler than the original DET 30™ without compromising on protection level, DET30™ Summer Cool is an anti-bacterial and reusable cotton mask featuring an inner layer treated with peppermint oil to enhance breathability and help you stay cool during the hotter months. The mask is white in color to avoid trapping extra heat. Regular and small sizes are available.

Masks are our first line of defense against invading pathogens, so it is important to take proper care of them when they are not being used. Our mask envelopes help ensure that your reusable mask stays in good condition and lasts as long as it is meant to. Made of 100% cotton, the DET Mask Envelope features the same anti-bacterial and water-repellent treatment as the DET30™. Buy our mask envelope online today and keep your DET30™ cotton mask clean and fresh on the go.
